The VIDZ cap has been reached so you can no longer swap. It's pretty difficult to estimate what the price of 1 atmos is. This is due to a variety of factors such as round 1 and round 2 will have differing prices as well as considering the burned VIDZ.
How can you have a cap on the VIDZ swap when you know exactly how many VIDZ were created ahead of time, and control exactly how many of the new coin is created? So it was essentially a race to see who burned their VIDZ first? That wasn't rules you mentioned initially. So another bait and switch from you? Why am I not surprised.
The only fair way to handle a swap is to have a set proportion set aside for VIDZ owners.
Does the scammy behavior ever end with you?
